Summary
Ruptured corpus luteal cysts can be identified by specific computed tomography (CT) findings. These include an enhancing cyst wall, high-attenuation contents, and surrounding fluid, aiding in diagnosis.
Area of Science:
- Radiology
- Gynecologic Imaging
- Emergency Medicine
Background:
- Corpus luteal cysts are common in reproductive-aged women.
- Ruptured corpus luteal cysts can present with acute abdominal pain.
- Accurate CT diagnosis is crucial for appropriate management.
Purpose of the Study:
- To characterize the computed tomography (CT) imaging features of ruptured corpus luteal cysts.
- To identify specific CT findings indicative of this condition.
Main Methods:
- Retrospective analysis of CT findings in six surgically confirmed cases of ruptured corpus luteal cysts.
- Evaluation of cyst size, shape, wall characteristics, content attenuation, and presence of peritoneal fluid.
Main Results:
- Cysts averaged 2.8 cm in diameter.
- Cyst walls showed strong enhancement, often discontinuous.
- Cyst contents and surrounding peritoneal fluid demonstrated high attenuation.
- Peritoneal fluid was noted in all cases, particularly around the adnexa.
Conclusions:
- CT findings suggestive of ruptured corpus luteal cysts include an enhancing rim, high-attenuation contents, and high-attenuation peritoneal fluid.
- Focal interruption of the cyst wall and periadnexal fluid are additional supporting signs.
- Suspicion for ruptured corpus luteal cyst is warranted with these CT findings.
